This memo provides information for the Internet community. It does not specify an Internet standard of any kind. Distribution of this memo is unlimited. Copyright Notice Copyright (C) The IETF Trust (2007). With current Network Mobility (NEMO) Basic Support, all communications to and from Mobile Network Nodes must go through the Mobile Router and Home Agent (MRHA) tunnel when the mobile network is away. This results in increased length of packet route and increased packet delay in most cases. To overcome these limitations, one might have to turn to Route Optimization (RO) for NEMO. This memo documents various types of Route Optimization in NEMO and explores the benefits and tradeoffs in different aspects of NEMO Route Optimization.

IETF proposed Network Mobility (NEMO) Basic Sup-port Protocol (BSP) to support network mobility. NEMO BSP is an extension of Mobile IP v6 (MIPv6), and inher-its all the drawbacks of MIPv6 (like inefficient routing, high handover latency and packet loss rate). Satellites equipped with several IP-enabled devices is an example of network mobility in space networks. In this paper, we propose an IP-diversity based network mobility architecture called SINEMO, and show that SINEMO can exhibit better perfor-mance than NEMO BSP in satellite IP networks. 1.

IETF has proposed Mobile IPv6-based Network Mobility (NEMO) basic support protocol (BSP) to support network mobility. NEMO BSP inherits all the drawbacks of Mobile IPv6, such as inefficient routing path, single point of failure, high handover latency and packet loss, and high packet overhead. To address these drawbacks, we proposed an IP diversity-based network mobility management scheme called Seamless IP-diversity based NEtwork MObility (SINEMO). In this paper, we develop an analytical model to analyze and compare the signalling costs of SINEMO and and NEMO BSP. Our analysis shows that SINEMO reduces the signalling cost by a factor of two when compared to NEMO BSP.

Abstract — Mobility in packet networks has become a critical issue in the last years. Mobile IP and the Network Mobility Basic Support Protocol are the IETF proposals to provide mobility. However, both of them introduce performance limitations, due to the presence of an entity (Home Agent) in the communication path. Those problems have been tried to be solved in different ways. A family of solutions has been proposed in order to mitigate those problems by allowing mobile devices to use several geographically distributed Home Agents (thus making shorter the communication path). These techniques require a method to discover a close Home Agent, among those geographically distributed, to the mobile device. This paper proposes a peer-topeer based solution, called Peer-to-Peer Home Agent Network, in order to discover a close Home Agent. The proposed solution is

NEtwork MObility (NEMO) handles mobility of a set of mobile nodes in an aggregate way using one or more mobile routers. NEMO introduces several advantages, such as reduced signaling, increased manageability, reduced power consumption and conservation of bandwidth when compared to individual host mobility. NEMO Basic Support Protocol (BSP), the IETF standard for NEMO, suffers from a number of limitations, like inefficient route and increased handoff latency. Most of the recent research efforts on NEMO have concentrated on solving the problem of inefficient route resulting in several route optimization schemes to solve the problem. To choose a route optimization scheme, it is very important to have a quantitative comparison of the available route optimization schemes. The objective of this article is to survey, classify and compare the route optimization schemes proposed in the literature over the last five years. We classify the schemes based on the basic approach for route optimization, and compare the schemes based on protocol overhead, such as header overhead, amount of signalling, and memory requirements. We conclude that performance of the classes of schemes has to be evaluated under criteria such as available bandwidth, topology of the mobile network and mobility type.

... location management scheme with pointer forwarding for wireless mesh networks. LMMesh integrates routing-based location update (location routing) and pointer forwarding by exploiting the advantages of both methods, while avoiding their drawbacks. It considers the effect of the integration on the overall network cost incurred by location management and packet delivery. By exploring the tradeoff between the service cost for packet delivery and the signaling cost for location management, LMMesh identifies the optimal protocol setting that minimizes the overall network cost on a per-user basis for each individual mesh client, when given a set of parameter values characterizing the specific mobility and service characteristics of the mesh client. We develop an analytical model based on stochastic Petri net techniques for analyzing the performance of LMMesh and a computational procedure for calculating the overall network cost. Through a comparative performance study, we show that LMMesh outperforms both pure routing-based location management schemes and pure pointer forwarding schemes, as well as traditional tunnelbased location management schemes.

Abstract—As portable devices are gaining more popularity, maintaining Internet connectivity anytime and anywhere becomes critical, particularly for mobile and vehicular networks. Network mobility (NEMO) and Internet Protocol mobility are gaining more and more importance. In this paper, we develop a Session Initia-tion Protocol (SIP)-based mobile network architecture to support NEMO for vehicular applications. We propose to form a mobile ad hoc network (MANET) by the mobile hosts (MHs) inside a vehi-cle or a cluster of vehicles. The MANET is connected to the outside world via a SIP-based Mobile Network Gateway (SIP-MNG), which is equipped with one or multiple external wireless interfaces and some internal IEEE 802.11 interfaces. The external interfaces of the SIP-MNG support Internet connectivity by aggregating user traffic to and from the Internet. In addition, exploiting the session information carried by SIP signaling, the SIP-MNG supports

In the context of mobile and pervasive networking, it is not uncommon to experience frequent loss of connectivity. Con-gestion control algorithms usually mistake resulting packets losses for congestion events and unnecessarily reduce their network usage. We propose an enhancement to the TCP-Friendly Rate Control (TFRC) protocol to overcome this is-sue. Our contribution proposes to suspend the data transfer, in a way similar to Freeze-TCP, when an upcoming discon-nection is predicted. Furthermore, a probing mechanism is introduced to enable fast adaptation to new network condi-tions. We present a description of the additional freezing and resuming mechanisms. This proposal has been implemented in ns-2. Simulation results are thus compared to the regular behavior and show encouraging improvements.

Abstract. Mobile IP and Network Mobility are the IETF proposals to obtain mobility. However, both of them have routing limitations, due to the presence of an entity (Home Agent) in the communication path. Those problems have been tried to be solved in different ways. A family of solutions tries to improve the routing by locating closer Home Agents making shorter the communication path. These techniques require a method to discover a close Home Agent from the Mobile Device. We proposed peer-to-peer based solution, Peer-to-Peer Home Agent Network, in order to discover a close Home Agent. This paper defines the necessary mechanisms to make this solution secure based on a mechanism named Secure Join Procedure. 1
